AUSWIRKUNGEN DER DURCH OXIDATIVE AMMONOLYSE CHEMISCH VERÄNDERTEN BRAUNKOHLE AUF DIE BODENBIOLOGIE.

In long term-incubation tests effects of blended amounts of chemical changed (N-modified) brown coal on the microbiological turnovers are investigated in various dump substrates. The results characterise this humus fertilizer as poor in noxious substances and as a long lasting acting organic soil improving agent including a N-fertilising effect. [ABSTRACT FROM AUTHOR]
